Must be a bug in Autodesk Inventor HSM that I just thought I would share with others who are experiencing the same problem. ![]() Wow it worked! which seems quite strange as my first tool was a flat end mill. The solution I found that worked for me was to add a 1mm radius to the corner radius for the rest machining option of the second pocket operation. I was not going to give up so I started playing around with some settings. Was I doing something wrong or is there a bug in the software.Īfter doing a bit of research on the web, where there were a couple of people with the same problem and trying a few of the suggestions nothing seemed to work. By right clicking on the 2nd pocket in the CAM browser and selecting generate toolpath I was greeted with another dialog box the selected operation has a valid toolpath. To my surprise, it did not work as expected and when I selected simulate I got the message no valid toolpath. Tool diameter was 12mm and tool corner radius was 0mm as the first tool was a flat end mill ![]() On the geometry tab, I used the rest machining option and inputted the tool size for the last cut. I ran into an issue the other day with machining a 2D pocket with a DIA 12 flat end mill as shown below and leaving radial stock of 1mm to finish off with a smaller tool.Īfter the first 2D pocket I duplicated the command in the CAM browser and edited it by changing the tool to a DIA 8 flat end mill for removing the remaining stock left by the previous operation. This makes the rest calculations simpler and more effective.Īutodesk Inventor HSM Rest machining using 2D pocket A good practice whenever possible is to use a tool whose diameter is slightly smaller than the smallest feature to be machined. This is far more efficient than re-machining the entire part with a small tool just to create a few small features. They do this by calculating what stock has been previously removed and comparing it against the finished model. Rest tool paths only remove material left by previous machining operations. Rest Milling is an acronym for remaining Stock required to be machined.
